Hiding her pregnancy and divorce, she stopped licking and the general panicked

When the prince learned that the courtyard wall was built, he left the palace immediately and was very satisfied after seeing it.

Just thinking about the fact that the walls are made of steel structure makes me feel so safe.

"Cousin, when will everything your friend has prepared be ready?"

"And the materials for the hot air balloon you asked me to make are all ready. Would you like to go and take a look?"

"Also, I have another request. Can you ask your friend to buy some more steel bars?"

"I'm thinking, if we build a wall like this at Hutou Pass and keep them out, wouldn't the people inside the pass be spared from suffering?"

Su Yujiao's eyes lit up. Yes, doing this would eliminate the danger at the source.

If Hutou Pass could be guarded well and all the poisoners could be kept out, the people would not suffer.

"Let me think."

"Hutou Pass is too close to the Southern Xinjiang Kingdom. If we build directly there, I'm afraid it will attract their attention."

"If they discover our actions in advance, I'm afraid they will also take action in advance, or do something bad behind the scenes, secretly sending one or two Gu people into the customs to harm others."

The prince thought for a moment and said, "Then we should build it inside the pass. People from the Southern Frontier Kingdom can't get in, and they can't see what's going on inside from outside the city."

"Even if the city walls are high, they still won't be able to find it as long as they are far enough away."

Su Yujiao nodded: "This method is feasible."

"But this will have to be done after Chu Zhongyuan and Chen Yunniang are in Southern Xinjiang."

“Otherwise, it might not be useful.”

"If they have already hidden in Daming, then building a wall at Hutou Pass will be useless."

"Also, transporting the materials is a major challenge. If we use ordinary transportation tools, I'm afraid Chu Zhongyuan and his Gu people will attack before the goods arrive."

“So, we have to use trucks to transport it, because it’s fast and can be loaded.”

"But trucks don't belong to this era. Can they really be seen openly in front of the public?"

"Before, I rode my motorcycle secretly at night, on small roads."

"It's quite fast, but every few steps we'll come across a city gate. We have to wait until daybreak to enter the city before we can continue our journey."

"Also, you have to use a horse-drawn carriage in the city. Once you leave the city and reach a remote area, you can switch to a motorcycle."

“It will still take up quite a bit of time.”

"If the road is unobstructed, then the speed can be truly improved."

The prince thought for a moment and said, "The people are just curious, but they may not be unable to accept it."

"If anyone asks about the origin of something, I will take responsibility for it and will never involve my cousin's wife."

Su Yujiao hesitated for a while. In this critical moment, she really couldn't care less.

"In that case, I'll ask Boss Wang to buy some more materials."

"Each wrinkle can be transformed into a shelter."

"The area doesn't need to be too large, the building can be built higher, and the conditions don't need to be too good, as long as it's able to hide."

"That way, if a Gu person really attacks, the people can temporarily hide in the shelter and wait for rescue."

"This will prevent the Gu army from becoming larger and larger."

"After all, if we lose one, the other side will gain one. The change in numbers will be terrifying."

The prince nodded frantically after hearing this: "Excellent, excellent, this way we can protect as many people as possible."

"I'll go back and draw up a detailed plan."

"By the way, cousin, can your motorcycle travel long distances?"

"Can you buy a few more?"

"Is it difficult to buy a car like that in your place?"

"I want to equip the Black Tiger Guards with a few so they can deliver messages faster."

"The more information we have, the more we can prepare."

Su Yujiao nodded: "Okay, motorcycles and trucks are not a problem, as long as there is money."

"But weapons are not available. I need to obtain them through special channels."

"I'll ask later if I can get more weapons."

"That's great, thank you, cousin."

"Let's go and try to make a hot air balloon and see if we can succeed."

“Now that the materials are ready, it’s quick to assemble.”

"it is good."

The two arrived at the warehouse, where the embroiderers and craftsmen were busy.

Su Yujiao took a set of necessary cloth and bamboo strips and gave some instructions to the craftsmen.

"You do this, then that..."

In about a quarter of an hour, a giant bamboo frame was made, and then the canvas was fixed to the spherical frame, and it was done.

"There's a basket hanging underneath. People stand on it and light the kerosene, hoping to get airborne."

"really?"

"That's natural."

"How to land?"

"A hot air balloon rises by heating the air inside it, and to descend you have to do the opposite."

"The descent is achieved by releasing the heat within the sphere."

"As long as the fire here is extinguished or reduced, it will gradually fall."

"There's a rope hanging from the edge of the basket. When it's almost reaching the ground, several people pull it together and secure it to a stone pillar or a heavy object."

Su Yujiao said as she looked around and pointed to a stone lion somewhere and said, "That stone lion is a great fixture. It definitely won't be dragged away by a hot air balloon."

"Are you wondering how a hot air balloon controls its direction?"

The prince nodded.

"In fact, the air is layered, and the direction of airflow at different altitudes is different. By ascending or descending to different altitudes with a hot air balloon, the direction of the airflow can be changed."

The prince did not understand some professional terms, but that did not stop him from admiring Su Yujiao.

My cousin’s wife knows so much!

Originally he didn't quite believe that the big ball could fly, but now he completely believes it and looks forward to flying with it.

"Cousin, can I go up and fly for a bit?"

"Not yet. I need to practice first. Find two people to go up with me so they can learn how to operate it."

The prince thought for a moment and said, "Let's find two people with high martial arts skills. They can protect my cousin's wife if something unexpected happens."

Su Yujiao nodded, safety is still the most important thing.

Although she can travel through time, others cannot.

Su Yujiao thought about it and was still worried. After all, the hot air balloon was crudely made and not professionally made. If an accident happened, wouldn't she be hurting others?

So she found three thick hemp ropes, each one hundred meters long, and tied them to the stone lions.

In this way, it can only rise higher and cannot fly around.

"Okay, this is much safer."

"Let's go, go up and try it."

The prince repeatedly warned: "You must protect the county lady's safety."

"Yes."

As the ignition was ignited, the hot air balloon slowly floated up, and then rose higher and higher. Su Yujiao stood on the hot air balloon and saw the whole picture of the capital, and even further away.

The prince's neck was sore from looking up, but he was reluctant to blink. Although the people busy in the warehouse didn't dare to run out to look, they should also stretch their necks to look at the sky outside.

"It flew away."
